Where are you using pos? Why do you need pos? Based on the message you are printing, what values do you need?

i have seen this in one of the post

Remember that when you copy code from forum posts, you’re also copying the errors.

for no, key in invalid_records:

        val=dictionary\[key\]

        print(f'Unexpected format {key} : {val} at position {index}')  

        is_invalid=True

but i am getting error You should have a for loop that iterates over invalid_records.

6

What is no being used for?

invalid_records = find_invalid_records(**dictionary)

for key in invalid_records:

        val=dictionary\[key\]

        print(f'Unexpected format {key} : {val} at position {index}')  

        is_invalid=True

i am getting this error -You should have a for loop that iterates over invalid_records.

Please post your full updated code so I can test.

Did you fix indentation errors in this block of code from your initial post?

I’ve edited your post to improve the readability of the code. When you enter a code block into a forum post, please precede it with three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add the backticks.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Instructions do not ask you to write pass anywhere.

I don’t get the same error. Are you sure you’re getting this error?

When I test your code I get this error:

  1. You should print Unexpected format '<key>: <val>' at position <index>.

Check the spacing and punctuation of this line.

You’re on the right track

12

checked still getting same error

You should print Unexpected format '<key>: <val>' at position <index>. (where <key>, <val>, and <index> should be replaced by the current key, value and index) inside your for loop.

Check it again.

Please share your updated code.
